THANK YOU ALL!

I have looked up the Amazon 30% industrial product, a Spectrum Chemical 30%, Fisher and Flynn (1.0 Normal HAc = 6%) products.  I think now I can make my case that there are a number of ways to go here other than glacial that are vastly safer and don't require separate storage.

I'm providing them the various options and my recommendation that they go any way but glacial.

There's a 5% solution manufactured by Ricca that you can purchase through Fisher.

I was so tired and frustrated when I asked for a dilute HAc source last night.  I should have been more precise.  

Someone already suggested vinegar. I usually suggest vinegar to colleges and schools where the use is small and its student work.  But this is a professional studio doing extremely high quality work, often for major artists.  They don't want any contamination with other trace chemicals and need an exact concentration of HAc.   But while these are professional artists, they sure aren't lab-trained chemists.  

And they mix up a fresh solution almost every day so the it would mean they would need a gallon bottle of vinegar every couple of days.  And I really don't want a bottle of glacial being handled every day in this studio.

A secondary issue is they will already have the limit of 3 large flammable storage cabinets and be only about 20 gallons under the OSHA 120 gallon limit for combined Category 2,3,& 4 solvents storage allowed in their fire area. 

I'll be happy if I can just find a source diluted enough to store in an acid cabinet and give them a little less chance of injury.  The eye wash and shower will be right next to where this is done.  

Oh, and Kodak sells a stop bath solution that is ~80 %, but it is very expensive and full of additives they don't want.

I need a source of acetic acid that is not in glacial form and both flammable and corrosive. It is used in photography and in various printmaking processes and usually at a 1:20 dilution. I can't have artists who don't even have fume hoods working with the glacial stuff.

Sigma had an 80% form that is not flammable but it is discontinued. Even a lower dilution would be good. Thanks guys.
